EPAWSS Eagle passive / Active Warning and Survivability System

With Boeing, the F-15 manufacturer, as prime contractor and integrator, the Epawss system is expected to include a new digital internal radar warning receiver, upgraded chaff-and-flare dispenser and a new fiber-optic towed decoy. The new system will also address "capability gaps as threats evolve," ACC officials say. "The threat environment is becoming congested and contested [and] F-15s need a modern EW system to remain viable in the future operational environment."

The emergence of Digital Radio Frequency Memory technologies also has frustrated allied EW technology, driving a need for upgrades. Using DRFM, an adversary can swiftly replicate signals, allowing for fast and accurate jamming in the air battle.

Though ACC officials say TEWS "lacks performance to counter current/future threats," Epawss introduction into service is beyond the future years defense plan, or beyond 2020. Installs for developmental testing aircraft are slated for fiscal 2017, the Air Force acquisition officials say.

The service is also procuring a long-wave infrared search and track (IRST) for the F-15C aircraft, which are primarily dedicated to air superiority missions. This IRST will provide beyond-visual range identification for enemy formations, allowing for operators to distinguish the number and possibly type of aircraft in formation at extended range.
